In a magnetic sector (single-focusing) mass spectrometer, it might be reasonable under some circumstances to monitor one m/z value, to then monitor a second m/z, and to repeat this pattern in a cyclic manner. rapidly switching between two accelerating voltages while keeping all other conditions constant is called peak matching.

a) derive a general expression that related the ratio of the accelerating voltages to the ratio of the corresponding m/z values.
b) use this equation to calculate m/z of unknown peak if m/z of the ion used as a standard, cf3+ is 69.00 and the ratio of vunknown/vstandard is 0.976034.
(c) based on your answer in part (b), and the assumption that the unknown is an organic compound that has a mass of 143, drnw some conclusions about your answer in part (b ), and about the compound.
